Valence  electrons  are number  of the  electrons  in  the   outermost   shell of  an  atom
silicon  has  4   valence  electrons
oxygen  has  2  since  in SiO3^-2  they  are  3  this  make  valence   electrons  to  be   6
SiO3^-2  have   negative  charge of  two  thes  means  has   two  extra electrons hence   has  2  valence  electrons

How many ions in 6.41 moles of K2O? Please show work.
Oksana_A [137]
1. Convert the number of moles to number of particles (divide 6.41 by 6.022 x 10^23)

2. K2O dissociates into three ions (2 potassium ions and 1 oxide ion), so multiply the result from step 1 by 3 to get your answer

Freon, a very useful refrigerant, is produced in the following reaction:
Svetach [21]

Answer:

The chemistry will need 2*10⁶ moles of antimony trifluoride.

Explanation:

The balanced reaction is:

3 CCl₄ (g) + 2 SbF₃ (s) → 3 CCl₂F₂(g) + 2 SbCl₃ (s)

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:

  • CCl₄: 3 moles  
  • SbF₃: 2 moles
  • CCl₂F₂: 3 moles
  • SbCl₃: 2 moles

You can apply the following rule of three: if by reaction stoichiometry 3 moles of freon are produced by 2 moles of antimony trifluoride, 3*10⁶ moles of Freon are produced from how many moles of antimony trifluoride?

moles of antimony trifluoride=\frac{3*10^{6}  moles of freon*2 moles of antimony trifluoride}{3 moles of freon}

moles of antimony trifluoride= 2*10⁶

<u><em>The chemistry will need 2*10⁶ moles of antimony trifluoride.</em></u>
